My pool was crystal clear with only a bit of residual algae on the sides/bottom. The cholrine level very low and so shocked -- it immediately turned murky green. Any advise? I don't think this is normal as its never happened before. My PH levels were low normal at the time.

I was told by my pool company that anytime you get green water after adding chlorine that means you have iron or other heavy metals in your water. You have to treat the iron with a specific product to remove it or you can get permanent staining on your pool surface.

the advice is right on for metals in your pool. read and follow all label directions on the remover you choose, overdosing can cause other problems. BE sure to let the water circulate for at least 24 hour before adding chlorine. IF you have a cartridge filter be diligent on taking it out and rinsing it off at least 4-8 times daily to keep the color from reentering the pool, until you have removed the metals.

I recently had a new pool heater installed, and since then I have been having the same problem, the water turns green the moment I put the chlorine in. Is there a specific product that will eliminate the iron or metals from the water ?

Right after I dumped shock into the pool it turned more green then before. I think the big this is that it shows that the shock was working as it should. Killed off the crude in the pool and it starts to float around which makes it more green. You probably also got more crude floating on the top. Keep the filter running 24 hours and it will start to clear up as the cholrine works to kill/clean things off.

I had the same thing happen right before my eyes. Shocked my pool and it immediately turned green and kind of hazy/cloudy. Just put the pool up (at that time) about 1.5 weeks ago. I do believe I have some sort of a metal problem even after putting in 2 bottles of metal-out (on different days.) I have a 24x4x4 above ground metal framed pool. How much metal remover is appropriate? It's hard to find specific information on this. I think mine is growing worse by the minute because I vacuumed today for several hours and not having the filter pump going (due to the vacuuming) has made my life much worse. I can actually see the rusty color on top. Long story......I've upped pH, lowered pH, had to add cal hardner, algaecide, metal out and 2x stabilizer. It's crazy. Every time I get one thing right, something else goes wrong. Exasperated!
Anybody been through this? HELP!

I meant to add that I have a saltwater generator also. It appears to be working fine (the digital readout always says it's fine). BUT, I tested my water and my total chlorine is ok, but my free chlorine is extremely high. How can my pool be green, cloudy and also kind of browinsh all at the same time? This is bizarre. I have read that if your free chlorine is more than your total, then you have to shock. Well, I put in 7 gallons of bleach and I'm still with the same problem. What in the world? I just added more stablizer because I checked it again and it's low. I probably already have about 300$ in chemicals and this pool hasn't even been up a month yet (about 3 weeks). Good grief!
